Author David Mitchell is best known for his sci-fi novel "Cloud Atlas" but his latest book couldn't be more different. "The Reason I Jump" is a translation of a memoir originally published in 2007 and written by then-13-year-old Naoki Higashida -- a Japanese teen on the autism spectrum. Mitchell and his wife KA Yoshida, who have a son with autism, translated the text into English. Mitchell also provided the book's introduction.
